Emacs? Gak! You want them to waste the whole semester
learning an editor? Notepad is perfectly acceptable.
There's probably a version of gedit that runs on Windows.

The Windows native port is fine, but you do need the 
MS assembler and compiler executables (and ml.err, the
assembler error file).

Why not just show them how to write out a script by giving them 
a simple example to edit, something like:

ocamlc -c file1.mli
ocamlc -c file2.mli
ocamlopt -c file1.ml
ocamlopt -c file2.ml
ocamlopt file1.cmx file2.cmx -o program

and explain the ordering requirements. 

There are several auto-makers for Ocaml (as mentioned in other
emails) .. but using these hides understanding of how the
ocaml tools work.

I would tend to provide a simple but not trivial problem,
and get them to write it in a familiar procedural style .. then
show how to convert it to a functional style, and what the
advantages are. So you'd want to pick a problem which is 
amenable to both kinds of solution.

EG .. convert loops to tail recursions, convert inner 
recursions to tail recursions, replace variables
with arguments, continuation passing, HOFs, etc.

One possible project is a small interpreter .. it has 
plenty of scope for variations, and has the advantage
of being interactive without requiring graphics.
